Application filed November 9,1904. Serial No. 232,036.

To @ZZ whom, t may concern:

Be it known that I, WILLIAM FAGAN, a citizen of the United States,residing at Abbott, in the county of Hall and State of Nebraska, haveinvented a new and useful Hay-Stacker, of which the following is aspecification.

This invention relates to hay-stackers, and has for its principal objectto provide a novel form of stacker in which the parts may be readilyadjusted for the delivery of the load at any desired point. v

A further object of the invention is to provide a hay-stacker in whichthe carrier is provided with a detachable back piece that travels withthe load carrier or platform during a portion of the upward movement ofthe latter, the back piece stopping immediately in advance of thedelivery-frame, while the loadcarrier continues its upwardmovement.

A still further object of the invention is to provide a novel form ofload-carrier, including a main carrier-frame and a back piece formed ofseparate sections, and to provide means for locking and unlocking' saidseetions.

A still further object of the invention is to provide a novel form ofdischarge frame which may be adjusted vertically as the height of thestack or rickincreases and may further be adjusted to alter its angle tothe horizontal in accordance with the build of the rick.

W ith these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and particularly pointed out in the appendedclaims, it being understood that various changes in the form,proportions, size, and minor details of the strueture may be madewithout departing from the spirit or sacriiicing' any of the advantagesof the invention.

lln the accompanying drawings, Figure 1 is a perspective view of ahay-stacker constructed in accordance with the invention. Fig'. 2 is asectional elevation of the same. Fig. 3

is a view similar to Fig. 2, illustrating' the position assumed by theparts when the carrier arrives at the point of discharge. Fig. 4 is adetail sectional view, on an enlarged scale. illustrating the means forlocking and unlocking the carrier and its back piece.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

The device forming the subject of the present invention is mounted onsills 10, having suitable runners 11 to permit the apparatus to behauled from place to place. The sills 10 are disposed in parallelrelation, and from the front sill extend two obliquely-disposedskid-beams 12, that are connected at a point intermediate of theirlength by a cross-bar 13. The cross-bar 13 forms a part of a strut-frame14, that is supported by the rear sill 10, said frame being' stronglybraced by diagonals 15, and from the upper portion of said strut-frameextends a pair of bracing-beams 16, that are connected to the upperportions of the skidbeams 12, said bracing-beams being provided atintervals with perforations 17 for a purpose hereinafter described.

Extending 'from the front of the cross-bar 13 is a pair of spacedguide-bars 20, these serving to guide a slidable discharge-frame 21. Theframe 21 includes a central beam 22 and, side beams 23, that areconnected at the bottom by a cross-bar 25 and at the top by a pair ofbars 26 and 27, the frame being' further braced by diagonals 28.' Thebottom crossbar 25 is extended and lits behind the skidbars and is heldfrom displacement by a pair of auxiliary guide-bars 30, that are securedto said skid-bars. The upper bar 27 slides on the front edges oftheskid-beams,and the crossbar 26 serves to support a discharge-grate 32.The discharge-grate 32 is formed of a plurality of spaced bars connectedby transverse bars 3A and 35, the latter being' connected to the bar 26by suitable hinges or other pivotal connections. To the opposite ends ofthe crossbar 34 are connected the ends of links 36, said links havingperforations 37 for the passage of securing-pins 38. The pins 38 arepassed through the perforations 37 and the perforations 17 of thebracing-beams 16 and permit the adjustment of the discharge-grate to anydesired angle. This discharge-fran'ie may be raised or lowered by ahoisting-cable 40, connected at one end to the lower portion of the bar22 and passing' from a suitable sheave Ll1 on the cross-bar 13, thelower end of the cable being attached to a suitable plate or otherfastening' at or near the lower portion of the main frame. By this meansthe dischargeframe may be raised at intervals. as the height of the rickg'radually increases, it being' unnecessary to carry the load to theextreme top of the skid-frame at each operation.

The carrier includes a back frame L13 and a carrying-platform 414e, bothof which are preferably grate-like in form in order to reduce theweight, although in some cases the platform and the back piece may beformed of solid planks or sheets of material where the device isemployed for the hoisting of dierent classes of material.

The back piece 43 includes grate-bars and cross-beams 46 and 47. Thecross-beams are connected to side bars 48, and near each of the latteris arranged a pair of slightlyspaced bars 49, that are disposed inparallel relation with the grate-bars. To each of the side bars 48 isconnected the opposite ends of a guide-bar 50, that serves as a meansfor limiting the movement of the carrier-platform with respect to theback piece.

The carrier-platform includes grate-bars that are connected bycross-bars 52 and 53, these in turn being connected together by sidebars 54, that are rearwardly extended and engage the outer faces of theside beams 48 of the back piece and the sides of the skidbars, theseserving as guides for the carrier during its movement toward thedischargepoint. To each of the side bars is secured a truss-frame 55,each truss-frame being provided with a small sheave 56 for the receptionof a hoisting-cable 57. The cables are secured at one end to projectingarms 58 at the top of the skid-beams and thence pass over the sheaves 56and around sheaves 59 near the top of the skid-frames anddown toguiding-sheaves 60 on the rear sills 10, at which point they may beconnected to a draft animal or animals.

Between each pair of bars 49 is pivoted a locking-tongue 62, the lowerend of which is pressed outward by a loop-spring 63 and is adapted toengage with the rear edge of the cross-bar 53 of the carrier-platform,said crossbar being preferably reinforced by a metal sheathing 65. Thetongue 62 is slotted, and through said slot extends a pin 66, that iscarried by a lever 67,'pivoted on a pin 68, the rear end of the pinextending between the skid-frame and the side bars 23 of thedischarge-frame. To each of the side bars of the discharge-frame issecured a cam 69, said cams being placed a distance below the uppercross-bar 27 about equal to the height of the back carrier, and as thecarrier-frame is traveled upward the levers 67 are engaged by said camsand the back carrier is disengaged from the carrier-platform.

To the front sill are secured small posts 70, preferably provided withbracing-bars 71, and these posts project slightly beyond the lines ofthe skid-bars, as indicated in Fig. 2, and serve as stops which engagethe crossbar 47 and limit downward movement of the back of the carrier.

In the operation of the device the carrierplatform assumes the positionshown in Fig. l, and the hay or other material is loaded thereon in theusual manner. The draft-animals are then started, and the stress on thecables 57 iirst raises the front of the carrierplatform until it assumesthe angleillustrated in Fig. 2, the rear bar 53 engaging against thelower ends of the locking-tongues 62, and then the carrier-platform andback piece start on their upward movement. The upward movement continuesuntil theV levers 67 come into contact with the cams 69, whereupon thelocking-tongues are moved from engagement with the cross-bar 53, and bythis time the upper portion of the back piece of the carrier has arrivedat a point adjacent to or in alinement with the top of thedischarge-frame, being at this time merely in contact with the upper bar27 of said frame, as shown in Fig. 3. The carrier-platform beingunlocked from the back piece then continues its upwardmovement, theround end of the rear bar 53 riding on the side bars 49 of the backpiece and being held from displacement by the auxiliary guide-bars 50.rlhe upward movement of the carrier-platform is checked when the rearbar 53 engages the ends of said guidebars 50, and by this time theplatform has arrived at the' position shown in Fig. 3, being then inalinement with the discharge-shelf 32, and the load slides off bygravityin the usual manner.

It is obvious that the discharge-frame may be adjusted from time to timeas the height of the stack increases, and it will therefore beunnecessary to raise the load to the same height throughout the stackingoperation,

lthis saving considerable time and labor in the building of the riclzs.The discharge-shelf may` moreover, be adjusted to any desired level, andwhen the device is to be hauled from place to place the discharge-shelfmay be locked in position by a hook 73 in order to prevent accidentaldisplacement. During transportation the carrier-platform may be foldedback against the backing-piece and may be tied or otherwise secured inplace.

Having thus described the invention, what is claimed is 1. In ahay-stacker, a skid-frame, a carrier slidable thereon and including aback piece and a platform, and means for disconnecting the back piecefrom the platform in advance of the arrival of the latter at the pointof discharge.

2. In a hay-stacker, the combination with a skid-frame, of a carrierincluding a separable back piece and platform, and means fordisconnecting the back piece from the platform and retaining said backpiece in position to form a guide for the material during furthermovement of the platform.

3. The combination in a hay-stacker, of a skid-frame, a carrierincluding a back piece and a platform, means for separating the backpiece from the platform and retaining' said back piece in position toform a guide for the material, and a platform-guiding means carried bysaid back piece.

4. The combination in a hay-stacker, of a skid-frame, a discharge-frame,cams carried by the discharge-frame, a carrier including a separableback piece and a platform` and locking-tongues for holding the backpiece and platform to each other, said tongues being movable tounlocking position by the cams.

5. The combination in a hay-stacker, of a skid-frame, a carrierincluding a separable back piece and a platform, pivoted tongues forlocking the back piece and platform together, levers connected to saidtongues, a vertically-adjustable dischargeframe, and cams carried bysaid discharge-frame and disposed in the path of movement of the levers.

6. The combination in a hay-stacker, of a skid-frame, avertically-adjustable dischargeframe supported thereby, adischarge-shelf carried by the frame, means for adjusting the angularposition of the shelf, and a carrier guided by the skid-frame.

7. The combination With a skid-frame, of a vertically-adjustabledischarge-frame, a pivotally -mounted shelf carried by saiddischarge-frame, means for locking the shelf in adjusted position, acarrier carried by the skid-frame, a back piece forming a part of thecarrier, and means for arresting the vertical movement of the back piecein advance of thel completion of the upward movement of the carrier.

8. The combination in a hay-stacker, of a skid-frame, a carrierincluding a back piece and a platform, and means for connecting anddisconnecting the carrier and platform, the extent of vertical travel ofsaid carrier being greater than the extent of travel of the back piece.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two Witnesses.
